IMPORTANT!
Read and follow these instructions
for adjusting the pultruded rail
system disconnect. Failure to
follow these instructions may
result in diaphragm leakage during
pumping or guide rail damage.
Step 1: If disconnect elbow
and sealing flange were ordered
separately, the proper diaphragm
gap must be set. Complete factory
assembled systems are factory
preset and require no adjusting.
Gap-setting Procedure:
1) Loosen guide arms on each
side of discharge elbow.
2) Insert loose sealing flange into
guide arms.
3) To set the top 1/8" gap, insert
the loose red rubber ring gasket
in between the sealing flange
and discharge elbow to act as
a spacer.
4) C-clamp sealing flange to
discharge elbow to hold
required gap (2 required,
snug parts together without
tightening).
5) Rotate each guide arm
to ensure the protruding
"block" on each guide arm
is up against the sealing
flange rib and the guide arm
opposite block side is against
the sealing flange hanger rods.
Torque bolts as follows:
3" systems: 40 ft/lbs
4" & 6" systems: 140 ft/lbs
6) Remove c-clamp(s) and
rubber gasket. Test gap by
pulling out on bottom of the
sealing flange. If the flange
is adjusted properly, it should
not pull back out of set
position more than 1/16". Test
disconnect by pulling up on
eyebolt (sealing flange should
release easily).
Step 2: Attach supplied chain
leg to achieve a three-point lift.
Test the balance of the pump by
adjusting the location of the
shackle in reference to individual
chain links. The pump must be
level to function properly.
WARNING: If the sealing flange
end of pump is raised above
the horizontal, the guide rail
may be damaged upon lowering
the pump. Ensure pump is
horizontal before lowering the
pump into basin.

Installation
Instructions
1. Concrete Basin(s)
Pour one or two concrete systems
(one for pumps and control, etc.
and one for valves, if required)
or obtain precast concrete rings.
A 45-degree slope may be poured
around the inside perimeter of
the basin at the bottom to
prevent solids buildup providing
the slope does not interfere
with the discharge elbow and
pump locations. Before beginning
the installation, refer to the
Installation Data as found in the
Hydromatic Engineered Products
Catalog.
Follow the Installation Data
taking into account the location
of the discharge pipe, inlet pipe,
controls, vent pipe, and anchoring
requirements of the discharge
elbow(s). (All of the above concrete
work to be done by others.)
2. Discharge Elbow Installation
See Installation Data for the
proper location of the discharge
elbow on the basin bottom. Either
cast 5⁄8" anchor bolts into basin
bottom protruding 2" from basin
floor with 5⁄8" lock washers and
nuts securing, or drill holes for
expansion lag screws to secure
elbow to basin bottom. Each
elbow requires four anchors (all
furnished by others). Each elbow
must be level. Length of anchors
embedded in concrete varies
with materials used, but must
be sufficient to withstand the
weight, torque, and thrust loads
imposed by the pump.
3. Discharge Piping
(All supplied by others)
Install vertical discharge piping
modules to elbow using bolts,
nuts, lock washers, and gasket.
NOTE: When increasing
the pipe size at the discharge
elbow an eccentric flanged
reducer coupling may be
required to avoid interference
with the guide rail. See
Installation Data.
Install remainder of the sump
discharge piping. This typically
includes a vertical run of
piping appropriately sized and
configured to mate with the
vertical discharge piping, a ninety
degree elbow, and a horizontal
run of piping appropriately sized
and configured to mate with the
valve box or main piping. Install
horizontal run extending through
the wall of basin. Secure vertical
run to the vertical discharge
piping using the appropriate
method (i.e., flange, weld,
gasketed collar coupling) and
grout all piping extending through
basin walls.
California to cause cancer, birth
defects or other reproductive
harm.
System Description:
In a Hydromatic Pultruded Rail
System, the pump is raised and
lowered in the basin using a
noncorrosive fiberglass I-beam.
A unique, patented hydraulic
sealing flange at the pump
discharge allows the pump to
be connected and removed from
the discharge elbow with ease at
any time without entering the
wet well. There is no need to
disconnect any piping or electrical
connections to remove a pump for
inspection or routine maintenance
checks. A typical system will
operate on float control switches.
A bottom float control will turn
off the pump(s). An additional
float control per pump is then
used to turn on the pump(s). In a
multiple pump station, the pumps
are automatically alternated
if using a standard Hydromatic
panel. Also, additional float
controls may be used to
indicate height and/or low
water sump conditions. The
general equipment for a
simplex and duplex system
includes the following:
Simplex Duplex
One pump Two pumps
One discharge Two discharges
Elbow assembly Elbow assemblies
One hydraulic Two hydraulics
Sealing flange Sealing flanges
One guide rail Two guide rails
One lifting chain Two lifting chains

Installation
Instructions
NOTE: If using flanged
connections, be certain that
adequate clearances are
provided throughout for the
installation of bolts, nuts, lock
washers, and gaskets.
If total run of vertical piping
exceeds twelve (12) feet, install
a piping brace at the approximate
midpoint of the piping. Secure
brace (i.e., U-bolt with angle iron
strap and angle iron extensions) to
both piping and wall of basin.
4. Basin Cover(s)
The basin cover for the sump
and valve box can either be
poured concrete or precast.
If Hydromatic door and frame
assemblies are used, locate the
concrete openings with respect
to the discharge elbow mounting
studs as shown in the Installation
Data. If the covers are poured,
place the door and frame assembly
inside the concrete form and
position per installation data.
Anchor straps are provided on
the door frames to secure them to
the concrete. If precast covers are
used, remove anchor straps from
frame before installing into covers.
Either cast four
3
⁄8" anchor bolts
into the top of the precast cover or
drill holes for expansion lag screws.
Use either
3
⁄8" nuts or stainless
steel bolts to secure door and frame
assembly to cover. If valves are
to be inside the wet well, provide
access ways as required for the
piping and valves to access piping
shut-off valves (see Installation
Data for general dimensions of
access ways). Access ways must be
covered and secured with tamper-
proof hardware (by others).
5. Guide Rail Installation
Install the pultruded guide rail
(I-beam) by attaching the lower
end of the guide rail to the
slotted lugs on the top side of the
discharge elbow. Two
3
⁄8" x 2"
bolts, one rectangular washer, lock
washers, and nuts are provided
with the discharge elbow parts
package. At the top of the guide
rail, plumb and then fasten the
guide rail to the door & frame
assembly or other suitable
bracket, using the four
1
⁄4"
x 1 stainless steel cap screws.
If Hydromatic door and frame
assemblies are not used, obtain
suitable upper guide rail brackets
(by others) to locate and support
the rail(s). A flat surface 4" wide
is required for each rail.
6. Intermediate Guide
Rail Bracing
Sump depths of 9'6" and greater
require intermediate guide rail
bracing. The braces mount on
the vertical discharge pipes with
U-bolts which are sized according
to the discharge pipe size. The
number of guide rail braces
required are as follows:
Sump Depths
9'6" to 18'0" 1 guide rail brace
required
18'6" to 27'0" 2 guide rail
braces required
27'6" to 30'0" 3 guide rail
braces required
On depths requiring more than
one brace, space the braces
equally on the pipe and tighten
U-bolts. Match drill two
5
⁄16" holes
through the guide rail flange and
attach with two
1
⁄4" x 1" stainless
steel bolts, nuts, and lock washers
provided with braces. Install with
bolt heads against the bracket.
7. Exterior Piping
Install the inlet hub(s) in side
of basin and install inlet piping
in hub and grout, or install inlet
pipe(s) directly into basin and
grout. Install drain pipe from
valve box (if required) to basin.
Slope pipe to give proper drainage
to basin. Install vent piping in side
of basin (if required). Extend
piping to a proper elevation above
grade (as required by plans and
specifications and/or local codes).
All piping furnished by others.
See Installation Data for typical
piping arrangement.
8. Pump and Sealing Flanges
Assemble the sealing flange (with
arms) to the pump discharge
flange using a gasket between the
two. Screw nuts with lock washers
on the bottom six studs. Slide
the guide rail connector through
the sealing flange ears and below
the top two studs protruding
through the back side of the pump
flange. Place the retainer clips on
the studs followed by lock washers
and nuts and follow illustration.
9. Pump Installation
Check all piping braces and
supports for proper installation
and tightness. Attach the lifting
chain assembly or cable to the
lifting eye(s) on the top of
the pump with the shackle(s)
provided. Lower the pump into
the basin with the guide rail
connector engaged over the
pultruded guide rail (I-beam).
Ensure that the chain or cable
does not interfere with the cord
cap assembly. Attach the upper
end of lifting assembly to the
hook provided on the inside of the
Hydromatic door and frame. The
heavy rubber sealing diaphragm
on the pump discharge should not
touch the discharge elbow flange
when the pump is being installed
or removed, or is installed but not
5
running. Its sole purpose is to flex,
due to water pressure when the
pump turns on, and form a leak-
proof seal between the pump and
the discharge elbow.
10. Float Switches
Mount the float switch mounting
bracket to the door and frame
assembly using
3
/8" - 16" stainless
steel screws. Include a dielectric
gasket (by others) between
dissimilar metals to avoid
galvanic corrosion. Allow excess
float cable to loop over mounting
bracket. The sump level is
controlled by Hydromatic
float switch controls. The
float is held in position in
the sump by a weight attached to
the power cord above the float.
The cord supports the float and
is adjusted for height from the
surface. Duplex systems use three
controls: one at all pumps off, one
set at one pump on, and one set for
both pumps on. Pumps alternate
operation on each successive
cycle with a Hydromatic Control
Panel. The alarm level is usually
set above the override (both
pumps on) level so the alarm
will signal only if the override
level is exceeded. However, some
engineers prefer to have the alarm
set below the override level as it is
possible for one pump to fail and
the other to operate on the override
level with the sump level never
reaching the alarm level. Do not
let floats rest against basin wall or
bottom or entangle with each other
or pump(s).
11A. Control Panel on
Mounting Stand
When the Control Panel mounting
stand is used, either cast four
1
⁄2"
anchor bolts into the concrete
cover, or drill holes for expansion
lag screws and attach stand
(bolts or lag screws furnished by
others). Insert power and sensor
cords from the pumps and all
float cords through the bushing in
the sump cover. Bolt the panel to
the panel stand. (Nuts, bolts, and
washers are not supplied.) Make
connections between the bottom
of the control panel and the basin
cover using flexible conduit and
conduit seals (by others). When
installing pump power cords,
make certain that the cords do not
rub against the pump or bottom of
the basin. Shorten cords to suit the
installation. See Bulletin Q-701
for the Installation and Service
Manual on the electrical Control
Panel system.
11B. Control Panel Mounted
Remote from Basin
If the Control Panel is remotely
located, instead of on the mounting
stand at the basin, install coupling
through basin wall. Screw
protective bushing from inside
basin into coupling (all furnished
by others). Make connections
outside station using wiring,
conduit seals (potted) and conduit
to remotely located Control Panel
(conduit and seals not furnished).
Insert the power and sensor cords
through the coupling provided
with bushing. Grout in coupling
going through sump wall (by
others). When installing pump
power cords make certain that
cords do not rub against pump
or on bottom of basin. Shorten
cords to suit the installation.
See Bulletin Q-701 for the
Installation and Service Manual
on the electrical Control Panel
system.
Electrical Connection:
Make all connections in compliance
with N.E.C. and/or local codes.
Connect the control panel ground
wire to a good ground. Ground
wire must be grounded properly
per N.E.C. and/or local codes. All
electrical connections are to be
made by a qualified electrician.

Removing Pump from Basin for
Servicing:
WARNING: Before handling
these pumps and controls,
always disconnect the power
first. Do not smoke or use
sparkable electrical devices or
flames in a septic (gaseous) or
possible septic basin.
To remove a pump from a
standard installation (control
panel mounted on basin cover),
the power to the control panel is
first turned off. Close the plug
valve. Disconnect the power cords
and sensor cords in the control
panel from their terminals. Lift
out the pump from the basin
by means of the chain or cable.
6
Disconnect the flexible conduit,
power and sensor cords from the
control panel. Pull the pump cord
down through the pipe coupling
while holding the cord on the
underside of the basin cover so the
cords do not fall into the basin. For
reinstalling the pump, reverse the
above procedure.
Removing Float Controls
for Replacement:
To remove a float for replacement
from a standard installation
(control panel mounted on basin
cover), the power is first turned off
to the control panel. Disconnect
the float leads from the terminals
in the control panel. Disconnect the
flexible conduit from the control
panel. Remove the flexible conduit
and the float control leads from the
control panel. Pull the pump cord
through the pipe coupling while
holding the cords on the underside
of the basin cover so the cords do
not fall into the basin. Remove
flexible conduit from potting
head. Break out potting from the
potting head and remove the float
wire. Remove float cord from
float cord mounting bracket and
remove float from basin. Replace
3900 float by reversing removal
procedure. Repot the leads in
the potting head according to
N.E.C.and/or local codes.
For the removal of the pumps
and float controls from system
with the control panel mounted
remote from the basin cover,
see the Pump Installation and
Service Manual.
WARNING: Before handling
these pumps and controls, always
disconnect the power first. Do
not smoke or use sparkable
electrical devices or flames in

septic basin.
Pump
Troubleshooting
The following is a list of common
problems and possible solutions.
Refer to Pump Installation and
Service Manual for any necessary
adjusting, dismantling or repair
work required on the pump.
For Control Panel troubleshooting
chart, refer to the Control
Panel Installation and Service
Manual Q-701.
Pump runs but does not pump
down the basin with the selector
switch on either Hand or
Automatic position.
1. Impeller may be clogged.
Amperage higher than name
plate will indicate this.
2. Pump rotation may be wrong.
Reversing any two line leads
on three phase pumps will
reverse the rotation.
3. Discharge plug valve may
be closed.
4. Plugging anywhere from
impeller to sealing flange. This
is evident if no water runs
out of sealing flange after
raising the pump. Pull the
pump from the basin to find
the clog.
5. Plugging beyond the sealing
flange. This is evident if water
does run out when pump is
operating when disconnecting
the sealing flange from the
discharge elbow. Remove the
check valve, clean out cover
and plug valve and other
piping, if necessary, inside
valve box to find clog.
Reassemble all valves and
piping. If the basin is still
not pumped down after the
pump is lowered again and the
sealing flange is reconnected,
proceed in a logical manner to
locate and clear the plugging.
6. Discharge head may be too
high. Check elevation against
design point of pump.
7. Improper discharge flow.
Check for correct impeller
size and proper voltage.
8. Check for possible broken or
clogged forced main.
Basin level is pumped down
with selector switch on Hand
position, but is not pumped
down with selector switch on
Automatic position.
1. Floats are not hanging free in
the basin or are covered with
debris. Pump the level down
with the selector switch on
Hand, so that the floats can be
observed. Relocate and clean
all floats as necessary.
2. If this is a new installation and
original start-up, the floats may
be miswired into the control
panel. Recheck the wiring
diagrams and schematics in
the panel. If the start and stop
floats are hooked in reverse,
the pump will short cycle on
and off and will not pump the
level down.
3. Floats or alternator are
malfunctioning. Pull the floats
out of the basin, clean them
and lay them on the ground.
Lift up the stop (lower) float in
the left hand, the start (upper)
float in the right hand and with
the bulbs hanging free, turn
selector switch to Automatic.
Lower the left hand until the float
hits the ground and lies on its
side. Nothing should happen.
After lowering the right hand
in the same manner, the pump
should start. When raising the
7
right hand to suspend the float,
the pump should continue to
run. The pump should stop when
raising the left hand to suspend
the float. If this procedure
does not cause the pump to
operate as described, either order
new float switches or replace
alternator relay.
